The _validate_persist_docs method (lines 108-111) has a similar vulnerability to the one fixed in _validate_meta - it doesn't handle the case where v could be None (when persist_docs: is specified without a value in YAML). Consider applying the same null-check pattern for consistency and robustness. The same issue exists for _validate_dict (lines 99-106) used by the docs field.
